Differences between images of large adenoma and protruding type of gallbladder carcinoma.
[carcinoma of the gallbladder]
The
aim
of
this
study
was
to
investigate
the
differences
between
images
of
large
adenoma
of
the
gallbladder
and
the
protruding
type
carcinoma
of
the
gallbladder
.
A
retrospective
study
was
performed
on
130
patients
who
underwent
cholecystectomy
or
biopsy
for
gallbladder
polypoid
lesions
larger
than
10
mm
;
among
them
,
20
patients
were
malignant
and
110
patients
were
benign
.
Patients
'
details
including
ultrasonography
(
US
)
,
computed
tomography
(
CT
)
and
magnetic
resonance
(
MR
)
findings
were
analyzed
.
All
patients
whose
lesions
were
>
15
mm
by
US
,
had
CT
or
MR
scans
to
further
determine
the
nature
of
the
lesion
;
two
patients
who
were
suspected
to
have
a
malignant
lesion
due
to
their
large
tumor
size
were
benign
by
histological
examination
.
Distinct
differences
were
found
between
large
adenoma
and
protruding
type
of
gallbladder
carcinoma
.
There
were
distinct
differences
between
adenomas
and
the
protruding
type
gallbladder
cancers
,
and
there
was
a
pathological
basis
for
the
differences
.
Benign
tumors
had
a
more
homogeneous
texture
,
had
spaces
between
the
tumor
and
the
gallbladder
wall
and
a
relatively
normal
configuration
of
the
gallbladder
wall
.
Based
on
these
findings
,
certain
lesions
could
be
definitively
diagnosed
as
benign
adenomas
and
could
help
in
treatment
strategy
.
